    Using the latest Carrier Updates on outdated firmware, such as jailbroken devices who don't want to update, can offer boost in signal strength and more. You may receive carrier bundles from here.

    Here is how you set-up iTunes to be able to use them.

    Windows:

    Open Command Prompt and run:

    64 bit:
    Code:
    "%ProgramFiles%\iTunes\iTunes.exe" /setPrefInt carrier-testing 1
    32 bit:
    Code:
    "%ProgramFiles(x86)%\iTunes\iTunes.exe" /setPrefInt carrier-testing 1
    Mac:
    Code:
    defaults write com.apple.iTunes carrier-testing -bool YES
    Last but not least:

    • Download the appropriate file for your device and carrier.
    • Connect your device.
    • Hold down Shift/Command and Press “Check for Update” or “Update”.
    • Choose the .ipcc file.
